Uncut gemstones-Where is reward?

When I completed this mission by trading the uncut gemstones I stole for big jack. I launched and did some pirating, when I got back to base, I received an email again from big jack, thanking me and and saying something like :”Here’s your reward…”. Well I don’t see my reward anywhere…. What is the reward anyway? and why didn’t I receive it? I’m using the F14.6 version.
